General Mach Discussion / 3+2 Drilling

« on: July 29, 2009, 05:00:54 PM »

Hey,

I am trying to generate gcode for Mach3 that can do 3+2 drilling in different workplanes using Powermill and PM Post.  Getting PM Post to actually produce code to do this was tricky enough for me but for some reason it doesn't do it properly.  I can drill in the XY plane no problem, but for some reason when it positions itself to drill in the YZ plane it actually just drills down into XY plane again. 

Does anyone know of a way to create a subroutine of gcodes that can manipulate the workplanes and allow me to drill in them?

Regards,

General Mach Discussion / Bouncing Z axis

« on: July 01, 2009, 08:34:03 AM »

Hey,

I am trying to home my z axis on my positive limit switch, but for some reason when it hits the switch, the instant it moves off it goes right back up again into the switch.  I left it for a minute or two and it continued to bounce on and off the limit switch with no signs of slowing down or stopping.  The thing that gets me is that when I home on the negative z lim switch, it works perfectly.  None of the other limit switches are behaving this way either, only the z+.  I would say that it is almost like it is looping the homing function for z.  Also, the Reset button on Mach doesn't stop it. I need to turn the servo off, cut the power or close Mach altogether. 

Has anyone else had this problem?

General Mach Discussion / Right-Click Helper

« on: June 26, 2009, 11:10:00 AM »

Hey,

For some reason I can't activate the little character that pops up when you right-click on a button in the Mach3 interface.  It runs uses the Help.txt in the Help folder.   Is there some way to enable/disable it?

General Mach Discussion / Poor Axis Calibration

« on: June 01, 2009, 06:00:43 PM »

Hey,

I am having a problem calibrating my axis'.  When using the auto calibration feature of Mach3 I can't get it to be accurate to within 30 thousandths of an inch.  I don't think that its my measuring apparatus because it is accurate to one thousandth.  Also, it acts weird in that multiple calibrations will yield better results up to a point (about a 30 thousandth as an error) and then it gets increasingly worse and the error increases.  I tried messing around with some things and couldnt get better results.  What are some tips to getting better accuracy, i.e. configuration settings and geneally good practices? 

Thanks,
Tyler
